Explanation
Type of filter
OFF:
Filter is not used
LPF:
Low Pass Filter. Cuts the frequency region above
the cutoff, making the sound more mellow.
BPF: Band Pass Filter. Cuts the sound, leaving only
the region near the cutoff. This is useful for creating
sounds with a distinctive character.
HPF: High Pass Filter. Cuts the frequency region
below the cutoff. This is useful for creating percussion
instrument sounds whose character lies in the high
frequency region.
PKG: Peaking Filter. Boosts the region of the cutoff.
Using the LFO to cyclically modulate the cutoff fre-
quency produces a wah effect.
LPF2:
Low Pass Filter 2. This cuts the frequency region
Time
above the cutoff, but the filter sensitivity is half that
of LPF. This is useful when simulating instrumental
sounds such as acoustic piano.
LPF3:
Low Pass Filter 3. This cuts the frequency region
above the cutoff, but the filter sensitivity changes
depending on the cutoff frequency. This is useful
when simulating acoustic instruments, but produces
a different nuance than LPF2 even with the same TVF
Envelope settings.
* If "LPF2" or "LPF3" are selected, the Resonance setting is
ignored.
Frequency at which the filter starts to apply
Amount by which the sound in the region of the cutoff
frequency is boosted, applying a distinctive character
to the sound
* Raising this excessively may produce oscillation, causing the
sound to distort.
